Complex Patterns of Inheritance

Question 1

What is incomplete dominance?

Answer 1

Both alleles are EQUALLY DOMINANT,
producing a NEW PHENOTYPE (intermediate
expression of a trait, looks like a BLEND) e.g. red + white flower = pink flower

Question 2

What is codominance?

Answer 2

Neither allele is more dominant than the other and both are expressed equally in a new phenotype. e.g. Roan horse with both black and white.

Question 3

What is autosomal inheritance?

Answer 3

The inheritance of
traits whose genes are found on the autosomes (1-22)

Question 4

Types of genetic tests for autosomal traits?

Answer 4

Karyotype

FISH (fluoroscence in situ hybridization)

Gene Testing

Biochemical Testing
